Be it known that L EDWARD GOLD, a citizen of the United fitates, residing in the borough of Manhattan, city, county, and State of New Yorlnhsye invented certain new and useful Improvements in Gaskets g'lings, of which the following is a specification.

- My invention relates to gaskets for hose couplings, and 1sperticnierly adopted tor use in the mating ends or conpiere to? eteem.

hose.

It-has innit-s object to provide n zeens whereby the geeket may he more certainly held in 'piece,-end consists in providing the spring-retaining ring" which has tongues for engaging behind shoulders in the hore the projection D of the coupler Which such g skets are frequently equipped, with means Wnerehy the said retaining ring 15 more certeiniy heid in place in gasket during the act of inserting the gzisitet'in the coupler.

Other ohjects of myini ention are herein after set cot.

A desirable form in which myinvention -may be embodied is iiiustreted in the ac companying drawings, whefein,- Figure l tlustretes n portion of one con pler head haying a gasket therein With'my invention applied thereto shown in crosssection; Fig; 2 1s a side elevation of a retainingspring embodying my invention separate the gasket; Fig. 3 is e bottom yiew of a gasket having my invention applied thereto. 4

My invention ie illustrated in connection type wherein two mating heads are employed, each being a counterpart of the other, and each hen-lingo ,gasket'inits direct port. The drawing iliustretee one of the said coupler heads, end this comprises 5!, body A having a projecting arm B which carriesn lug C that engages over a. projec tion on the mating coupler corresponding to type new. a fixed gasket. It is provided with /o circumferential hand F haying an annular groove f which 15 seated in the body 6 of the msketto .vre'vent movement of the.

band relative to the gasket. The gasket has necessed portion at e which is Seated on if corresponding seat a in the coupler nor The gasket is usuall provided with an 111- 5 nor metal band oi frame G, and this hand implication nee "sewn 5, 515. e rie in.

The gasket E is of the Fntented Beea '2 51935 or frame togetliewwith the outer hand F serve the purpose of enabling the gasket tohold its shape under extreme heat and pressure and prevent it from spreading out.

The foregoing constructions form nopart of the present invention, which resides in on improvement in the means whereby the gasket is held in pos tion in the coupler here.

The gasket is provided with a split ring H, which is of motel hevingeufiicient spring so that when inserted in the gasket it will he spring pressedoutwardly. This-ring has spring tongues I each of which projects i'nweirdly from-the gasket and into the bore of the coupler and is provided with an outweirdly bulged portion-i which engages hehind a shouldera} inthe coupler. core and holds-the gasket in position.

According to my invention means tire pro: vided for increasing the spring of the tongues l} by forming slots Q g in the body of the gasket on each side of the spring tongues 1, and these extend substantially one hail the axial length of thering. The hody of the ring between two .e-djacent spring tongues l is extended substantially the full axial length of the ring between the cut away portions g g, and .in the construction illustrated, there being three spring tongues Lthere will be three of such extensionseuch of which forms short/tongues J. The seid tongues J increase the extent of cont-net between the ring and the gasket and consequently enable the ring to be more certainly held in place in the gasket. According to my invention I also provide means for preventing the ring H beingdisplaced While the gasket is being inserted. into position in the coupler. The said ringis provided with outward projections which as illustrated take the form of the-flange K with which "the outer edge of the ring opposite the spring tongues is provided. .The asket has a recess to receive the said projeetion, and this recess is illustrated as 2i circumferentioi groove L in which the outer end of the band G isseated, end which is preferably proflided with a straighted e shoulder 21 egnilnst which the edge oft e flange Kbeef s. It will therefore be perceived that the axial strain upon-the ring consequent upon its insertion in the bore of the coupler Will nothave theefi'ect of dispiecing thefsaicl ring in the gesket body, as the fienge K will hear against the straight ice edge Z, which acts as a stop to hold the ring inposition. For the purpose of assisting this effect, the ring is formed as a split ring having a split at h, and the ring is separated at this point for insertion in the gasket body, and when inserted it springs I outwardly so as to cause its flange to enter the groove in the ring. The ring is of such illustrates the only form, as modifications thereof within the limits of the appended claims will suggest themselves to the skilled mechanic, and may be employed.

I claim 'as my invention 1. In a gasket for hose'couplings, having a body portion adapted to enter a seat in a coupler head, a split ring adapted to be received within said gasket body and having pring tongues projecting from its inner side and adapted to extend in abore of the coupler and engage behind a shoulder therein and retain the gasket in its seat, means for increasing the spring of the tongues comprising forming the said. ring with grooves on each side of said tongues, said gasket formed with .a recess and a projection in the ring adapted to enter said recess, and the ends of said ring adapted to abut together when the ring isin place, whereby the ring is held in position in the gasket While the gasket is being seated in the coupler.

2. In a gasket for hose couplings, having a body portion adapted to enter a seat in a coupler head, a split ring adapted to be received within said. gasket body and said gasket also having means coiiperating with the coupler to retain the gasket in its seat,

means for holding the said ring in position while the gasket is being seated in the coupler, said means comprising a shouldered recess in the gasket and a flange in the ring adapted to enter said recess, the outer ed e of said ring flange abutting against said shoulder being limited in radial dimension to the thickness of the ring, and the ends of the ring adapted to abut together when the ring is in place whereby the ring is held in position in the gasket while the gasket is being seated in the coupler.

3'. In a gasket for hose couplings, having a body portion having a seat in a coupler head, a split ring having spring tongues projecting from its inner side and adapted to extend in a bore of the coupler and engage behind a shoulder therein and retain the gasket'in its seat, means for holding the said ring inposition while the gasket is being seated in the coupler, said means comprising an annular groove in the inner wall of said gasket nearits face, said groove having a substantially straight outer wall extending radially of the gasket, a flange formed on the outer edge of said ring by flaring the said ring outwardlyuthe outer edge of said flange abutting against the shoulder being limited in radial dimension to the thickness of the ring, the said. ring adapted to expand upon insertion in the gasket, and the ends of said ring adapted to abut together when the ring is in place whereby and by reason of the engagement of the outer edge of the flange on the ring .against the straight edge of the shoulder in the gasket the said ring is held in place a in the gasket While the gasket is being seated in the coupler.

In Witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
